Here you go, --Flutter-snap--! You can use this as your profile pic if you'd like, but I don't mind if you choose not to use it.

I know you said you wanted a gray background, but I didn't like the way the gray one looked, so I made the background a gradient! Hope you're fine with that :)

And as you can tell this was clearly inspired by artem11s, except not as good XD

EDIT: Here's the updated version of your profile pic, sorry for the mess up! I was kind of going based on your profile pic rather than the reference presented, so sorry!
